Result overview

Inconclusive

Outcome: The analyst should attempt subjective species identification at the genus level.

Reasoning: [Flag 1C] >3 candidate species matched with high stringency (identity ≥ 98.5%).

Identification of candidate species

Flag 1C: The analyst should attempt subjective species identification at the genus level
>3 candidate species matched with high stringency (identity ≥ 98.5%)

Candidate hits must meet ONE of these criteria:

Minimum alignment length 400bp
Minimum query coverage 85.0%

Candidate hits have then been classified as follows:

Classification Alignment identity Number of hits Number of species
STRONG MATCH ≥ 98.5% 36 7
MODERATE MATCH ≥ 93.5% NA NA
NO MATCH < 93.5%

Candidate species

Species Hits Identity E-value Database coverage
Wahlgreniella nervata 7 100.0% 0.0
Aphidinae sp. BOLD-2016 9 100.0% 0.0
Rhodobium porosum 11 100.0% 0.0
Ericaphis scammelli 2 99.4% 0.0
Ericaphis fimbriata 5 98.8% 0.0
Ericaphis sp. RFBAE098-09 1 98.5% 0.0
Wahlgreniella sp. BOLD:AAB6874 1 98.5% 0.0

Boxplot of BLAST hit identity percent grouped by genus

The boxplot above shows the distribution of BLAST hits identity within each genus. Each data point shows the alignment identity between the query sequence and reference sequence. The analyst may wish to refer to this figure when making a subjective genus-level identification for the sample.

Taxa of interest (TOI)

This sections shows the taxa of interest (TOI) specified by the sample submitter. Each of these taxa has been cross-referenced against the candidate species to determine if they might match the taxonomic identity of the sample. A blank row indicates a TOI that did not match any candidate species, meaning that it is unlikely that the sample matches that TOI.

Taxon of interest Match rank Match taxon Match species Match accession Match identity Database coverage
Aphidius ervi Did not match any candidate
Aphididae family Aphididae Wahlgreniella nervata KF285590 1.0

Reference sequence source diversity

This analysis evaluates how many independent sources have contributed to reference sequences for each candidate species. This provides a measure of confidence in the taxonomic annotation of references sequences. A sequence that has been annotated by multiple independent sources is more likely to have a correct taxonomic annotation.

Analyst evaluation

No candidate species to report on.

Intraspecies diversity

This section provides a phylogeny of the candidate reference sequences. The analyst can use this to make a subjective observation on how well the reference sequences are able to distinguish between species. If the phylogeny shows distinct clades for each species, we can be confident that the molecular data are capable of distinguishing between those species. However, if the phylogeny shows overlap between species, this reduces the capacity of the molecular data to confidently distinguish between those species. In some cases, we may see the query sequence falling outside of the adjacent species' clades, which indicates that our query species is not represented in the reference database, which could indicate a rare or novel species.

The phylogetic tree was constructed with FastME using the Neighbor-Joining method. Multiple-sequence alignment of the candidate reference sequences was performed using MAFFT. The visualization is rendered with TidyTree.
